Abstract
This study focused on the quantitative assessment of the vertical displacement velocities
retrieved using Sentinel-1 and Cosmo-SkyMed synthetic aperture radar images for the
Tengiz oilfield. Tengiz oilfield was selected as a study area because of its historically
reported continuous subsidence and limited up-to-date studies during recent years. The
small baseline subset time-series technique was used for the interferometric processing of
radar images acquired for the period of 2018–2020. The geospatial and statistical analyses
allowed to determine the existing hotspots of the subsidence processes induced by oil
extraction in the study area. Ground deformation measurements derived from the Sentinel 1 and COSMO-SkyMed satellite missions showed that the Tengiz oilfield continuously
subsided during 2018–2020 with the maximum annual vertical displacement velocity
around −77.4 mm/y and −71.5 mm/y, respectively. The vertical displacement velocities
derived from the Sentinel-1 and the COSMO-SkyMed images showed a good statistical
relationship with R2≥
0.73 and RMSE ≤3.68 mm. The cumulative vertical displacement
derived from both satellites for the most subsiding location also showed a good statistical
relationship with R2 equal to 0.97 and RMSE = ± 4.69. The observed relative differences of
measurements by both satellites were acceptable to determine the ongoing vertical
surface displacement processes in the study area. These studies demonstrated a
practical novelty for the petroleum industry in terms of the comparative assessment of
surface displacement measurements using time-series of medium-resolution Sentinel-1
and high-resolution COSMO-SkyMed radar images
